CUH-1116A - Not eating/ejecting disk - Rollers ok

Hi,

I am trying to fix a CUH-1116A which is not eating/ejecting disk. I opened it, cleaned the rollers and ensured the rollers where correctly linked with the little white stick between them.

When I pressed the eject button, I can ear 3x beeps.

The two little contact sensors seems to be working as the blue ray is slinding one time back and forth when white gears start turning.

Also shorting the 1st one or the 2nd one make the blue ray slides one time back and forth the same way as when the gears start turning.

I can totally insert/remove disk using the manual screw, but the disc is only read when all in at startup. If I fully insert disk while already spowered-up, nothing happens, disk is not read/spinned.

First though the little PCB with the motor and 2x sensors could be down, but reading thing here and there I realized it could come from many other reasons.

I have got a BDP-015 and checked two fuses just next to the large chip (blue “R270” and black “SB”) which are ok. Would like to know if there are other fuses to check?

Though I could get some help from some vets :)
